This model features a foldable head or body which lets you collapse it to a compact size—easy to carry in a bag or backpack. It also typically includes a USB‑rechargeable battery (Type‑C in many cases) so you don’t need to rely on disposable batteries while on the move.These features make it well suited for travel, camping, outdoor events, or just beating the heat when you’re on the go.

Depending on the specific model/brand, you’ll find features like multiple fan speed settings (e.g., 5 speeds or even “1‑100” adjustable speed in premium models) so you can choose from gentle breeze to stronger airflow. As for runtime, some foldable fans with built‑in rechargeable batteries are listed as delivering anywhere from ~5 to ~15 hours of use depending on speed and battery capacity.

• Charging: Use the included USB/USB‑C cable. Make sure to fully charge before your outing so you start with full battery capacity.
  
• Usage & speed: If you choose a higher speed or stronger airflow, the battery will drain faster—if you require longer use (e.g., during camping), consider starting on a lower setting to conserve battery.
  
• Cleaning and storage: If you use the fan outdoors (dust, dirt, camping environment), wipe the blades/grill and keep the unit dry. Store folded in a pouch or bag to protect it.
  
• Folded/Unfolded usage: Use as designed—some units may also stand on a desk or be used around the neck (with lanyard) when folded appropriately. '

• Battery care: Avoid storing the fan with zero charge for long periods; if not in use for a while, charge and store partially full to prolong battery health.
